Abstract (en)
The present invention provides a pseudo dual-port memory. The pseudo dual-port memory includes a single-port memory, a multiplexer, a timing control circuit and an output circuit. The multiplexer is configured to sequentially output a first address and a second address to the single-port memory. The output circuit is configured to receive output data from the single-port memory to generate a first reading result corresponding to the first address and a second reading result corresponding to the second address. The output circuit includes at least a sense amplifier and is configured to generate first data serving as the first reading result, and second data serving as the second reading result.
